Vacuum Cleaner Reviews

The industry standard in consumer products like vacuum cleaners is Consumer Reports and they go into insane detail about vacumm cleaners:

For example:
“Canister vacuum cleaners (35)
Nearly all canisters do a fine job of cleaning bare floors and on stairs, but carpets remain their toughest challenge. Top-scoring models combine impressive deep-cleaning with strong airflow through the hose for use with tools for cleaning upholstery and drapes. Most full-sized canisters tend to be heavier, bulkier and more expensive than uprights. Pay particular attention to our noise ratings if you have bare floors, which echo sound.z”

Or for small vacuum cleaners: “Small vacuums (1)
Like uprights and canisters, the best small vacuums tend to be ideal for cleaning carpets, the toughest and most common task. But none can deep-clean carpets like their larger cousins, so consider them as backup vacs.

Not Acceptable. Our tests found problems with Dirt Devil’s handheld Kone M0213 (L-code only) and similar M0212. These models threw particles of picked-up sand and glass out of their exhaust ports, posing a safety risk to testers’ faces and eyes.”
